Bench AI Assistant - WordPress Plugin

An AI-powered video discovery chat assistant built as a custom WordPress plugin for MyPromoVideos.

Live Demo: https://mypromovideos.com/video-inspirations/

What It Does

Users type a natural language prompt (e.g. "I need a fintech explainer video") and the assistant finds and displays the most relevant B2B marketing videos from a library of 200+ videos.

Features

  • Conversational chat UI built entirely in Vanilla JS (no React or Vue)
  • AI intent extraction via OpenAI GPT-4 (fallback: Google Gemini)
  • Video search using WordPress WP_Query on a custom post type (ulz_listing)
  • Progressive fallback search strategy (AND to OR to keyword)
  • Duplicate video removal (PHP + JS deduplication by ID and title)
  • Email gate: shows 3 videos first, captures email, then 9 per batch
  • Real-time lead logging to Google Sheets via Google Apps Script webhook
  • Every user search prompt logged to Sheets instantly (fire and forget)
  • Email backfilled into all matching session rows on submission
  • Mobile-first email form with touchend event handling
  • Session state persistence: email collected flag survives topic changes
  • Animated "More Videos" bar on landing page
  • Cache busting via WordPress version constant

How It Works

  1. User types a prompt to WordPress REST API (/bench-ai/v1/chat)
  2. AI extracts intent: keywords, tags, categories
  3. WP_Query searches ulz_listing CPT with progressive fallback
  4. AI re-ranks results by relevance
  5. First 3 videos shown, email gate appears, then 9 per batch after
  6. Search prompts and emails logged to Google Sheets in real time
